Step 1: Materials

For this project you will need:

- Any cool PCB (The thickness isn't really relevant so you can take the circuit you prefer. I took it from an old cd drive).
- Power drill (If you have a dremel, better).
- Drill bit to cut plastic.
- Sandpaper.
- Pen.
- Patience (not optional).

Optional:
- Soldering iron.
- Three hand or vice grip.

Step 2: Select the work zone and cut it

Now you need to choose what part of the circuit do you want to use. If the area has components, take out with the soldering iron.

Then, cut it.

Step 3: Mark and cut(again)

Afterwards, draw the pick outline in the PCB and cut it with the power drill or the dremel.

Step 4: Make it better!

Now look good, but not gorgeous. So, take the sandpaper and clean the both sides. Don't worry about the circuit, the sandpaper only erase the surface layer.
After that, sand the edge and finish the work.

im probably going to do this soon, but i would need some kind of plastic coating because the solder on it is led, and a lot of the times, i put my pick in my mouth to hold it while im doing something with both hands.

Would polyurethane work? Or is that just trading one health hazard for another? I've used polyurethane with other projects where I need a durable clear coating and it's worked pretty well. But not anything I'm putting in my mouth. I'd like to make a few of these (lots of guitar players in the family). If anyone knows more about polyurethane than I do, would that be relatively safe?

I've got a set of these, but I'd urge guitar players to be careful with them. They have absolutely no give, which is bad for your strings and usually your sound, and they'll scratch up your guitar something fierce. They'll scratch the pickguards too--which is what they're there for, but it still doesn't look pretty.
